Map Properties
Description: a tag that describes the layer data or nature (data type) of the map.
Map Layers: allows user to select the layer that the following actions will be applied to.
Disconnect: disconnects or closes the layer so that layer is no longer part of the map. To see that layer again you must reopen it.
Properties: the Layer Properties dialog box will be displayed allowing the user to view and/or edit the following properties of the selected layer:
|
Visible:

Minimum View Scale:

allows the user to set the minimum scale used to draw the selected layer.
|

Center On: allows user to select a portion of the layer to center on in the viewing area.
To Top: returns the view to the top of the map.
Area: displays the coordinates in degrees of latitude and longitude of the northwest (top) and southeast (bottom) of the entire map.
Center X: allows user to set an x coordinate used to center the entire map.
Center Y: allows user to set a y coordinate used to center the entire map.
Scale: allows user to set the scale for the entire map. Entering a larger number will cause more of the map to appear in the viewing area. Therefore each individual object will appear smaller.
Rotation: rotates the map in a clockwise direction relative to the north of the map in decimal degrees. The view angle affects the view of the map only. Image layers are not rotated. Use of this feature is not advised.
